摘要:

A method of calculating stresses and deflections for beams whose material creeps is presented in this paper. Complete tension creep test data at constant temperature are used to define creep characteristics of the material. Then by using Bernoulli's hypothesis of plane sections and the techniques developed earlier for interpretation of the relaxation creep tests, a method of beam analysis is shown. Stresses and deflections may be calculated for any desired time interval. This includes the time prior to the occurrence of the steady state creep. The latter aspect appears to have been ignored by others.
